Dressing Up the Past: Creating and Re-Creating Acadian Identity
During the early twentieth century, Acadian women dressed up in a costume based on the main character from Henry Wadsworth Longfellow’s 1847 epic poem Evangeline at nation-building events to symbolize the Acadian people and its past. Acadians came to consider the Evangeline costume to be the …

High pressure acadian metamorphism of the Straits Schist, Western Connecticut
… was undertaken to provide data on the Acadian Orogeny in the northern half of the western highlands of Connecticut. The Straits Schist, contained within the Connecticut Valley synclinorium, is structurally involved in portions of both the Hartland and Gneiss Dome belts, outlining …

Structural and Petrologic Evolution of Acadian Dome Structures in Southern Vermont
… evaluation of several different models for Acadian (Late Silurian to Middle Devonian) dome evolution in southern Vermont. Previous models considered diapiric uprise and composite nappe-stage crustal thickening and subsequent diapirism as likely causes of dome formation. Both of these …

Petrology of the Taconian-Acadian Overlap Zone, Hartland Belt, Western Connecticut
… at P-T conditions that are consistent with an Acadian (Devonian) metamorphic field gradient for this area. P-T conditions were calculated by simultaneously solving for a geothermometer and a geothermobarometer in low-variance assemblages. All of the possible equilibria for each sample were then …

Abundance and Nesting Success of Acadian Flycatchers (Empidonax Virescens) at Different Scales of Fragmentation in Illinois, United States of America
… communities in which the nests were located. Acadian Flycatcher nesting success increased with increasing nest concealment. Although Acadian Flycatchers preferred to build their nests in certain tree species, tree species was unrelated to nest concealment and nesting success. Most of the other …

Multidisciplinary analysis of a polymetamorphic terrane, western New England
… peak metamorphic effects in the west and Acadian (Devonian) peak effects in the east. In between, a complicated zone of overlap contains predominantly Taconian mineral assemblages that have been variably affected by Acadian processes. ⁴⁰Ar/³⁹Ar data presented here indicate that the timing …

STRUCTURAL AND KINEMATIC INVESTIGATION OF THE DADEVILLE COMPLEX-BREVARD ZONE CONTACT (SOUTHERN APPALACHIANS): POLYPHASE EMPLACEMENT OF AN ALLOCHTHONOUS TERRANE ON THE LAURENTIAN MARGIN
… and was accreted onto Laurentia during the Acadian orogeny (Devonian-Mississippian Periods); however, the mechanism and role of accretion during the Acadian orogeny is not well constrained. Three proposed emplacement mechanisms for the DC include: (1) orogen-perpendicular translation; (2) …

Stratigraphy and Tectonics: Multi-Disciplinary Evaluation of Tectonic Models For the Eastern and Southern Continental Margins of North America
… ~1.5 times faster than those of the subsequent Acadian phase. Subsidence rates during the Alleghanian phase were much slower than the preceding Taconic and Acadian phase. The decrease of subsidence rates from the oldest to the youngest orogenic event may reflect that the Appalachian lithosphere …

PALEOCLIMATE DURING DEPOSITION OF THE GREATER TWILIGHT PARK CONGLOMERATE, UPPER DEVONIAN, SOUTHEAST NEW YORK
The Acadian Foreland Basin formed from the collision of various exotic terranes with the continent of Laurentia, primarily during the Devonian Period. This created the southward propagating Acadian Orogeny. Formation of the basin and the cratonward-prograding Catskill clastic wedge promoted …

EMPLACEMENT OF THE DADEVILLE COMPLEX OF THE SOUTHERNMOST INNER PIEDMONT WITHIN THE 7.5 MIN. CUSSETA QUADRANGLE, CHAMBERS COUNTY, ALABAMA: CHANNEL FLOW, KLIPPE KINEMATICS, OR OROGEN PARALLEL TRANSLATION
… three orogenic periods, the Taconic, the Acadian/Neoacadian, and Alleghanian orogenies. The Inner Piedmont of the Appalachian Mountains within Alabama contains two distinct lithologic complexes, the Dadeville Complex, and the Opelika Complex separated by the Stonewall Line. These complexes …

Marine offshore to alluvial plain transitions within the "Chemung"-Hampshire interval (Upper Devonian) of the southern central Appalachians
… plain, respectively, are syn- to post-orogenic (Acadian), and were derived from the erosion of the Acadian Mountains to the east. Facies of the "Chemung" indicate deposition within three major, laterally adjacent environments. The predominating facies assemblage constitutes upward-coarsening …

Polyphase deformation and metamorphism in the Penobscot Bay Area, Coastal Maine
… metamorphism and granitic plutonism. D₁ (early Acadian ?) produced tight to isoclinal folds and an axial plane foliation that deform all three metasedimentary units and contacts between these units. These units and therefore the PGW and Bucksport terranes must have been together by the time of …

Across- and along-strike structural and geochronological variations of the Nashoba-Putnam and Avalon terranes, eastern Massachusetts, Connecticut, and Rhode Island, southeastern New England Appalachians
… America. These orogenies are the mid-Paleozoic Acadian orogeny and the late Paleozoic Alleghanian orogeny. The northeast-trending Nashoba-Putnam terrane, located in eastern Massachusetts and Connecticut is part of the Gondwanan-derived microcontinent Ganderia. It is in fault contact with …

Tectonic and geologic development of the Charlotte belt south central Virginia Piedmont
… suprastructure, a D₃ dextral shearing event (Acadian?-Alleghanian) forming the Brookneal and Clover shear zones bounding the Charlotte belt on the northwest and southeast, respectively, and a D₄ event (Alleghanian) that produced regional-scale northeast-trending open folds across the area. (4) …

K-Metasomatism in Uppermost Precambrian Rocks in West-Central Wisconsin and Southeastern Missouri

The Acadians of Southwest Louisiana
… and courageous people of French descent, the Acadians, were forcibly driven from the rich and fertile lands of Nova Scotia, and through almost incredible hardships and sufferings, were literally dumped upon populations which, in many instances, were either fearful or unprepared to welcome them …

Habitat use by nongame birds in central Appalachian riparian forests
… species richness showed no riparian influence. Acadian flycatchers and Louisiana waterthrushes were closely linked to the streams. Carolina wrens, American robins, and red-eyed vireos showed weaker but positive associations with the streams. Eastern wood-pewees, black-and-white warblers, pine …

Geology of the western boundary of the Charlotte Belt at Brookneal, Virginia
… results of the regional Taconic event, the late-Acadian event which terminates to the west in Brookneal, and the fault localized Alleghanian event, each of which resulted in faulting.

"Gender Fund" : creating a virtual mutual fund investing in firms with gender diversity
… During a financial research project sponsored by Acadian Asset Management² our team of 3 people investigated whether these conclusions were reliable. We adopted an approach comparing portfolios with at least one woman on board to portfolios with no women on board. However, our results on average …
